摘要
The present invention provides an imageable element including a lithographic substrate and an imageable layer disposed on the substrate. The imageable layer includes a radically polymerizable component, an initiator system, and a polymeric binder. The imageable element further includes a tetraarylborate salt. The presence of the tetraarylborate salt may provide improved imaging speed and may enhance press life due to better adhesion between the imageable layer and the substrate. The tetraarylborate salt may be present in the imageable layer, an interlayer, or a separate layer between the substrate and the imageable layer. The imageable element may be imaged and mounted on-press without a separate development step.
